argthe3rd,

Figured it out - In order for you to see just the sliced (filtered) number of rows, you must have the Column you use on the Slicer either as part of the Column in Row box or on the filter box. I added it in the Filter box and hid the row - now if I narrow the value in the Pivot table using the Slicer it shows just those rows with the value narrowed down by the Slicer. (in your example - add Doctor as part of the Filter and then if you click on the 50, it will just show the 50 patients).

Cheers!!
